Title: Improvements in or relating to Information Transmission Systems
IPC: H04L12/52
Filed: 1967-10-23
Abstract: 1,164,558. Digital transmission systems. SIEMENS A.G. 23 Oct., 1967 [24 Oct., 1966], No. 48058/67. Heading H4P. A data transmission system comprises a central control ZSt with a store in which the relationships between input and output devices, e.g. calling and called subscribers, are stored. The central control is connected to an input code converter ECW, which may convert from one out of n code to binary, via a line ECV and a programme channel EPK, and to an output code converter ACW via a similar line ACV and channel APK. Additional connections, e.g. IZL, IAL, ICV are provided between the central control and the code converters and within the central control so that it can transmit data from or to units within it in the same way that it transmits data from an input device to an output device. Thus, for example, a unit in the central control which is to transmit a signal from that unit to a subscriber sends a signal via IZL to ECW which identifies the unit and provides the corresponding binary address by way of which a corresponding section of central store SP can be reached. Via programme channel EPK the central control is engaged, which passes the address of the called output device to ACW which selects the device. The signal to be passed to the selected user is then fed to ACW for forward transmission. Word register WR connected to an address register AR allows the identification and selection of input/output units in the central control by means of addresses. A priority arrangement is provided to decide on the priority of input devices within and without the central control. The control unit may be time shared between the input devices, and includes a unit which recognizes different input devices and units within the central control.

Filed: 1975-12-02
Abstract: 1487020 Semiconductor devices ITT INDUSTRIES Inc 2 Dec 1975 [6 Dec 1974] 49406/75 Heading H1K A composite contact to a region of a planar semiconductor device consists on a metal layer and a silicon oxide coated layer of doped polycrystalline silicon the layers being ohmically connected to each other and each directly contacting the region. In the described embodiment, shown in plan in Fig. 3 and in section in Fig. 4 (not shown) such a contact is provided on the base zone of a silicon transistor. After formation of base, emitter and peripheral channel-stopping regions by oxide masked diffusion, and re-exposure of part of the base zone, phosphorous doped polysilicon is deposited overall and reduced by photoetching to a strip 1 at the periphery of the base, and a frame 5 constituting a field plate overlapping the channel-stopping region, and thermal oxide formed on the exposed silicon and etched patternwise to expose emitter and base contact areas. Metal is then vapour deposited overall and etched back to form emitter contact areas. Metal is then vapour deposited overall and etched back to form emitter contact 12 and part 13 of the base contact which overlaps the ends of strip 1. Because of the hardness of the polysilicon and the strong adherence of the oxide to it the chance of short-circuiting the emitter junction by inaccurate placement of wires thermocompression bonded to the metal contacts is reduced.

[Also in Division B8] A sealing element is formed in a container closure by depositing a liquid composition comprising a plasticized thermoplastic resin in the closure and heating the composition until it has at least partially gelled and is sufficiently plastic to be shaped, and shaping it with a moulding member the moulding surface of which is kept below 80‹ C. by the circulation of a cooling liquid through the member. The element may be shaped before gelling is complete but with the composition temperature sufficient to prevent it sticking to the moulding member, followed by further heating to complete the gelling. Alternatively the composition is heated to a temperature above that at which gelling is complete and is then shaped. The composition may contain P.V.C. and may be spread over the closure interior before heating by spinning the closure. Between the heating and shaping steps the composition may be cooled and re-heated.

Title: Piezo-Electric Transformer
IPC: H01L41/107
Filed: 1968-10-25
Abstract: 1,164,600. Piezo-electric transformers. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 25 Oct., 1968 [31 Oct., 1967 (6)], No. 50777/68. Heading H3U. A known transformer comprises a rectangularsection body B having input electrodes 9, 10 on its driving portion 6 and an output electrode 11 on its power generating portion 7, the portion 6 being polarized in the direction of its thickness and the portion 7 being polarized in the direction of its length, as denoted by the arrows. At the junction 8 between the portions 6, 7 there is a severe mechanical strain, which may destroy the body B, due to the abrupt change in the direction of polarization. The present invention overcomes this objection by causing the junction 8 to be not polarized or only weakly polarized, Fig. 2, where the length of the arrows denotes the degree of polarization; alternatively, Fig. 5, the direction of polarization may be caused to gradually change at the junction. One method of obtaining the Fig. 2 result is to provide additional polarizing electrodes 12, 13, Fig. 3, for polarizing the portion 7, these electrodes being both connected to one pole of the polarizing source, the electrode 11 being connected to the other pole. One method of obtaining the Fig. 5 result is to make the electrodes 10, 12 of different length, the portion 7 being polarized by connecting these electrodes to one pole of the polarizing source and the electrode 11 to the other pole. The portion 6 is then polarized by connecting the electrodes 10, 12 to the different poles of the source.
